A Knoxville jury has convicted 43-year-old Roderick Jermaine McAlpin of setting four fires inside his wife's home, after prosecutors said he torched three bedrooms and a closet and left the house with heavy structural damage. Knoxville Fire Department crews responded to put out the blaze, and McAlpin is set for sentencing on August 14, 2026.
Verdict And Prosecutors' Account
In a Facebook post, District Attorney General Charme Allen said prosecutors in the domestic-violence unit secured convictions after a two-day trial. Jurors found McAlpin guilty of arson, vandalism over $60,000, and aggravated criminal trespass. According to the post, he faces a minimum sentencing range of 12 to 20 years, and Judge Scott Green set the formal sentencing hearing for August 14, 2026.
Allen credited Assistant District Attorneys Joe Welker and Zac Sharp with trying the case and noted that assistant victim-witness coordinator Cindy Vanosdale and legal secretary Mary Loveless supported the prosecution. “Thanks to the expertise of our arson investigators, we were able to hold this offender accountable,” she wrote.
How Investigators Say The Fire Started
Local coverage from July 2025 reported that neighbors saw McAlpin climb through a bedroom window while his wife was away, and that video showed him moving a Ring camera shortly before the fires were discovered. Those reports said the blazes were set on mattresses in three bedrooms and in a master closet, and that Knoxville Fire Department crews knocked down the flames on the 2400 block of Larkwood Lane, according to WVLT.
Jail records from the Knox County Sheriff's Office show that McAlpin was bound over on the charges in July 2025 and went to trial at the end of June 2026.
His Record And The Evidence Prosecutors Presented
Prosecutors told jurors that arson investigators, using accelerant-detecting canines, identified ignitable liquids on three mattresses and in a bedroom closet, and they estimated roughly $137,000 in structural damage to the home. Those details appeared in the district attorney's Facebook post.
Court filings and an appellate opinion reflect that McAlpin has prior drug-related convictions that were upheld on appeal. The Tennessee Court of Criminal Appeals opinion lays out that background. Prosecutors indicated that his record, along with the trial evidence, is part of what they plan to highlight at sentencing.
What's Next
McAlpin is due back before Judge Scott Green on August 14 for sentencing. If the court follows the range outlined by prosecutors, he faces a lengthy state prison term. The district attorney's post did not include any comment from defense counsel.
Court dockets show the case moved from a bound-over status in July 2025 to a late June 2026 trial setting, according to the Knox County Sheriff's Office. For broader context, Knoxville fire investigators have been working several suspected arson cases this year as officials and residents talk about enforcement and prevention, a pattern that has shown up in local coverage of another arson case.
